摘要： PROBLEM TO BE SOLVED: To carry out a further detailed diagnosis of contents by limiting the number by judging a shape of the contents in a container or bag from X-ray projection images, taking out a specified content and projecting near infrared rays. SOLUTION: A shape of a contents of an object to be inspected 1 such as a bag or the like is judged from an X-ray projection image obtained by an X-ray projection apparatus 100. If an object to be furthermore investigated, i.e., a suspicious object or the like is present, the object is placed on a re- inspection movement rail 6' branching from an object movement rail 6. Near infrared rays are projected to suspicious object or the like object 14 taken out and set in a near infrared emission apparatus 13. Obtained signals are input to a near infrared spectrum monitor 17 and displayed in a spectrum. The spectrum is compared with spectra of samples to be identified which are registered in a computer beforehand, so that a substance of the object 14 can be identified in real time. The result is input and stored in the computer and also recorded in a recording apparatus 9.

摘要： PROBLEM TO BE SOLVED: To eliminate moving a dubious object by holding an irradiation part body of an X-ray generator to a holding body in a manner to be movable up and down, moving the irradiation part body down over the holding body when the holding body is placed on the ground, and irradiating X rays from near a surface of the ground. SOLUTION: An X-ray generator 2 of an electronic linac type has a voltage capacity of, e.g. approximately 950 keV, and is provided with an irradiation part body 4, a holding body 5, a magnetron 6 and a power supply box and operator panel 7 separately from each other. The irradiation part body 4 is held to the holding body 5 in a manner to be movable up and down, can move down to near a ground surface, and preferably can irradiate X rays from within approximately 2 cm of the ground surface. When a body 10 to be inspected is left as a dubious object on a road, the X-ray generator 2 is set to one side of the body 10 and a line sensor type X-ray detector 3 is set to the other side. The irradiation part body 4 can independently move to near the ground surface, and therefore X rays can be radiated from near the ground surface. The need of manually moving and contacting the body 10 is eliminated accordingly.

摘要： PROBLEM TO BE SOLVED: To make the weight of the whole of shielding material reducible in which its X-ray generator is integrated with its X-ray inspecting apparatus by constructing the structure of an X-ray shielding device to match with an X-ray radiation cone. SOLUTION: This apparatus comprises an X-ray inspection part and an image monitoring part, wherein the X-ray inspection part is provided with an X-ray generator 4, X-ray detector 5 and shielding device 8 made from lead. The device 8 is composed of a lower conical part 21 and an upper cylindrical part 22 and an X-ray generator shielding part 23, and is provided with a postal matter leading inlet/outlet corresponding to a door 11. The conical part 21 is shaped in correspondence with an X-ray radiation cone being the spred of X-rays radiated from the X-ray generator. In addition to the cone shape, another shape is also applicable. With the constitution adapted to the X-ray radiation cone and formed to cover the same, the weight of the whole shielding device can be reduced, and thereby a cost reduction is also attained.

摘要： PROBLEM TO BE SOLVED: To provide a fluoroscopic apparatus which enables X-ray photographing of a subject easily even at a narrow part or a high location while enabling displaying of fluoroscopic image information as image. SOLUTION: An X-ray detector has a shielding plate 13 with slits 21 adapted to pass X rays, a fluorescent film 10 which is arranged at the same position of the slits 21 and detects X rays passing through the slits 21 to emit light and a photo diode array 15 which is arranged behind the fluorescent film 10 to convert light emitted into an electrical signal and is moved sequentially by a value equivalent to each slit 21 to detect X rays. This achieves a thinner designing and a miniaturization and enables X-ray photographing of an object to be inspected easily even at a narrow part or at a high location while allowing displaying of fluoroscopic image information as image.
